The ground state spectrum for the case 𝑚 F S > 0 and in the limit that 𝑚 F S 𝑚 s o f t , where the mixing between the vector multiplet and hypermultiplet is small. The composition of the various states (see (2.15) and (3.15)) is a function of t a n 2 𝜃 = 𝑚 𝑒 / 𝑚 𝑝 . For example, in the heavy proton limit ( 𝑚 𝑒 𝑚 𝑝 ), 𝜔 is predominantly scalar-scalar, whereas in the opposite limit ( 𝑚 𝑒 𝑚 𝑝 ), 𝜔 is predominantly fermion-fermion.
